Key Identification Features
- The photobiont partners of Solorina crocea are arranged in two distinct layers within the thallus: a roughly continuous layer of green algae sits above a patchy cyanobacterial layer.
- Scanning electron microscopy study of fine ascospore structure has shown that each common arctic-alpine Solorina species has consistent, distinctive spore ornamentation.
- It grows in a foliose pattern, and its leaf-like structures feature visible vein-like markings.
- This anatomical trait is one of the key characteristics that links the species to the Peltigera genus, despite its unusual aquatic habitat and distinct overall morphology.
